Remove # $FreeBSD$ from Makefiles.

Add USES=xorg USES=gl, ports categories m

Add USES=xorg and USES=gl to ports in categories starting with 'm'
While here, try to sprinkle other USES (mostly gnome and sdl) as needed.

- Fix trailing whitespace in pkg-descrs, categories [g-n]*

Reset maintainership for obrien

Approved by:	portmgr

MASTER_SITES cleanup.

- Replace ${MASTER_SITE_FOO} with FOO.
- Merge MASTER_SITE_SUBDIR into MASTER_SITES when possible. (This means 99.9%
  of the time.)
- Remove occurrences of MASTER_SITE_LOCAL when no subdirectory was present and
  no hint of what it should be was present.
- Fix some logic.
- And generally, make things more simple and easy to understand.

While there, add magic values to the FESTIVAL, GENTOO, GIMP, GNUPG, QT and
SAMBA macros.

Also, replace some EXTRACT_SUFX occurences with USES=tar:*.

Rename mail/ patch-xy patches to reflect the files they modify.

Remove indefinite articles and trailing periods from COMMENT, plus minor
COMMENT typos and surrounding whitespace fixes. A few Makefiles where not
included as they contain Latin-1 characters that break the Phabricator
workflow. Category M.

- Support staging
- Respect CC

- Modernize port

Fix properties on pkg-plist

Add NO_STAGE all over the place in preparation for the staging support (cat:
mail)

The vast majority of pkg-descr files had the following format when they
had both lines:

Author: ...
WWW: ....

So standardize on that, and move them to the end of the file when necessary.

Also fix some more whitespace, and remove more "signature tags" of varying
forms, like -- name, etc.

s/AUTHOR/Author/

A few other various formatting issues

- remove MD5

- Remove unneeded dependency from gtk12/gtk20 [1]
- Remove USE_XLIB/USE_X_PREFIX/USE_XPM in favor of USE_XORG
- Remove X11BASE support in favor of LOCALBASE or PREFIX
- Use USE_LDCONFIG instead of INSTALLS_SHLIB
- Remove unneeded USE_GCC 3.4+

Spaces->tabs in the mail category.    

Add $FreeBSD$, which help me in problem reports.    

Convert category mail to new layout.  

Use ${MASTER_SITE_LOCAL}.    

The local-distfiles dir on ftp.freebsd.org was moved under ports/.    

Become the guinnie-pig and move all my Freefall ~/public_html distfiles   over
to the new ftp.freebsd.org local distfiles site.
